Point or Vector

Hello,

I have some trouble with if.

I have three reals, x0, y0 and w0.

If w0 is equal to 0, I would have the vectors P0(x0,y0), else, I would have the point P0(x0,y0).

Thank you very much for yours answers.

Salut Lionel!

Hmm, I think you have to specify your problem.

Saying that there is a "mysterious" if-command which delivers dependent on input a vector or a point .... which answer do you expect. ;-)

So I think for help it's better to post your file.

Hi Lionel!

I'm very sorry, but I misunderstood the problem.

Hi,

I put an example where P1 is a point or a vector.

Best Regards.

Both objects must be of the same type.
Maybe you can use "Condition to Show Object" to do what you want?

Ok, once again and sorry for the trouble.


I hope that I understand now correct.

In Algebra it does not work (for me), but in CAS (for me) it works.


I deleted my previous post, because the picture in graphic-window doesn't change by changing from "point" to "vector" so I was a little bit confused.

But the logical "proof" confirmed the change.
